COMPOSITE FABRIC.

fo (/.l yUzom. it lmay concern.'

Be it known that we, ERNEST STRAUSS and WILLIAM B. ERSKINE, bothcitizens of the United States, and residents of the city of New York,borough of Manhattan, inv

the county and State of New York, have invented a new` and ImprovedComposite Fabric, of which the .following is a full, clear, and exactdescription.

This invention relates toa new and improved composite fabric of theelastic type.

An object of the invention is toprovide a fabric which will be simple inconstruction7 strong, durable and inexpensive to manufacture.

A further object of the invention is to provide a composite fabric ofhigh elasticity, which will stretch readily without tearing thenon-elastic components thereof.

These and further objects, together with the construction andcombination of parts, will be more fully described hereinafter andparticularly set forth in the claim.

Reference is to be had to the accompanying drawings forming a part ofthis speciication, in which similar characters of reference indicatecorresponding parts in all the views, and in whichf Filgure 1 is aperspective view of the composite 4 fabric partially Fig. 2 is a topplan View of astrip of the composite fabric, and Fig. 3 is a verticaltransverse section'showing the relative position of the component partsof the composite fabric.

Referring more particularly to the sepaf rate parts, represents onelayer or4 com,- ponent part of the composite fabric, which may be of`any suitable fabric, such jas cotton or silk, preferably the latter. Thelayer 45 is turned over at its side edges, to form folds, Within theouter edges of which there are provided elastic threads 12 and 13, whichare made of any suitable material, such as rubber7 gutta-percha or thelike.

lintermediate the threads 12 and 13, and spaced apart therefrom, thereis provided an elastic layer or band 31, which lies adjacent the fabriclayer 45, and is made of any suitable material, such as rubber,guttapercha or the like. Covering the elastic layer .31 there isprovided a fabric' layer 8, which may be made of any suitable material,

such as cotton, silk or the like, and is of such a Width as to slightlyoverlie the fold ed-over edges of the fabric layer 45. The

completed Specification of Letters latent. Pgntnted It/Kim. 22, gjlfl.,Application filed .uly 2l, 1909. Serial No. 508,833.

elastic members 12, 13 and 31 are secured to the fabric layers 8 and 45by means of a .suitable adhesive material, such as cement or the like,with which they are coated on all sides, and with which the fabriclayers are coated on their` facing surfaces. The fabric layer 45 is alsocoatedwitli this adhesive material'along the folded-over side edgeswhich contact with the under surface of theV fabric layer 8. l

By reason of the method used in forming this composite fabric, thefabric layers 8 cilage or the like, and allowed to dry, eitherartificially or naturally. The side edges of the opposite side of thefabric layer 45 are then coated with the same adhesive material, andalso allowed to dry. rlhe fabric layer 8 is also coated on one side.with a suitable adhesive material, and dried. The elastic layer 3l ispreferably coated on both sides with the adhesive material, and dried,and the elastic threads12 and 13 are also coated, preferably on allsides, with a suitable adhesive material, and dried. The coating of thecomponent parts with the adhesive material may be done in any suitablemanner, such 'as by running the component vparts in contact with aplastic mass of adhesive material. The component parts are then placedon reels, which supply the material to a machine Whichl is particularlyde.- scribed and claimed in our co-pending application, Serial No.508,834, filed July 21, 1909, and which assembles the component parts intheir proper relation, and places the. elastic members under adistorting or eX- tenuating ltension, and subjects the assembled partsto a pressure, whereby they are adheredy together by reason of theiradhesive coatings. y

There is thus provided a composite fabric of the elastic type, whichwill be exceedingly lfoo strong, and Which Will stretch to aconsiderable extent Without injuring the textile members of thecomposite fabric.

Having thus described our invention, We claim as new and desire tosecure by Letters Patent A composite fabric, consisting of a strip offabric material, a strip of elastic material -thereon and of lesserWidth than the first strip, and elastic strings spaced apart from theedges of the elastic strip and substanf tially parallel with the saidedges, the edges of the first named strip being folded over on
